Come posso correggere gli errori del medico brew

Question

Sono un principiante quando si tratta di tutto questo, quindi perdona la mia incompetenza.

Quando eseguo brew Doctor, ottengo quanto segue. Qualcuno può aiutare?

[/usr/local]$ brew doctor 

Error: Setting DYLD_LIBRARY_PATH can break dynamic linking. 
You should probably unset it. 
Error: Some keg-only formula are linked into the Cellar. 
Linking a keg-only formula, such as gettext, into the cellar with 
brew link f will cause other formulae to detect them during the 
./configure step. This may cause problems when compiling those 
other formulae. 

Binaries provided by keg-only formulae may override system binaries 
with other strange results. 

You may wish to brew unlink these brews: 

libxml2

Directories in your path should not end in a slash. This can break other

/usr/local/git/bin/ 
[/usr/local]$

Error: Setting DYLD_LIBRARY_PATH can break dynamic linking. You should probably unset it. Error: Some keg-only formula are linked into the Cellar.

Questo chiede di disinserire il percorso di caricamento dinamico della libreria. Puoi farlo scoprendo dove lo hai impostato e rimuovendolo. Molto probabilmente, si dispone di una linea nel vostro ~/.bashrc o ~/.bash_profile che assomiglia export DYLD_LIBRARY_PATH=/some/path:$DYLD_LIBRARY_PATH

You may wish to brew unlink these brews: 

libxml2 

Quando i collegamenti Brew, è la creazione di un link simbolico per l'installazione. È come puoi avere python2.6. python2.7 installato ma python eseguirà uno di questi.

brew unlink libxml2

Questi sono i file residui provenienti da altre installazioni. Puoi eliminarli.

rm FILENAME

Error: You have uncommitted modifications to Homebrew's core. Unless you know what you are doing, you should run: cd /usr/local && git reset --hard 

Qui, vi sta dicendo che hai fatto le modifiche ai file Homebrew. Fortunatamente, Homebrew è memorizzato nel controllo di versione Git in modo da poter ripristinare tali modifiche.

cd /usr/local && git reset --hard

Error: Some directories in your path end in a slash. Directories in your path should not end in a slash. This can break other doctor checks. The following directories should be edited: /usr/local/git/bin/ 

La variabile PATH è dove il vostro computer cerca i programmi quando si digita nella riga di comando. Puoi vedere il tuo percorso con echo $PATH.

Gli standard dettano che tutti i percorsi in PERCORSO non devono finire in una barra. Quindi, homebrew ti sta chiedendo di aggiustarlo.

nano ~/.bashrc o nano ~/.bash_profile e cercare '/ usr/local/git/bin /' e rimuovere la barra finale.

Answer 2

Sono nuovo anche per preparare. Quando ho provato per la prima volta, ho finito con una lista di errori. Non tutti i necessitano di da risolvere per me per usare la birra come ne avevo bisogno. In particolare, ho potuto ignorare il

Unbrewed * were found in /usr/local/lib 

messaggi che stavo ottenendo. Credo che questi siano solo un problema quando il tuo uso di pacchetti installati brew interferirà con quelli che hai installato prima (nel mio caso, era NTFS-3g, non correlato ai miei futuri usi di brew).
